Ireally need with this can you answer the questions and say how you came up with it i'm begging you

A=30^2+ 2 x 30 x 26
A= 900 + 1560
A= 2460
so the surface area is 2460
v=1/3 x 30^2 x 26
v=1/3 x 900 x 26
v= 300 x 26
v=7800
so the volume is 7800
and the way the order of operations helped you is that you had to remember to always do the exponents before any of the other multiplication

Part A= 2701 in^2
Part B= 7800in^3

Ibelieve the answer is c i worked it out three times but if my answer is wrong someone correct me
